Turkey's state-run media says prosecutors are seeking more than 12 years' imprisonment for Barcelona's Arda Turan for a nightclub fight in which he reportedly broke the nose of a singer.

The fight between Turan and pop singer Berkay Sahin began after the midfielder allegedly made comments to the singer's wife.

Turan, who is on loan to Istanbul Basaksehir, allegedly later entered a hospital where the singer was being treated, brandishing a gun.

Anadolu Agency said on Monday that Turan faces a 12-and-a-half-year sentence. Other media said Turan was being charged with sexual harassment, possession of an unlicensed gun, deliberate injury and wilfully endangering public security.
